| | * | | | Using Symbian native mutex type in tst_bench_qmutexmread2011-03-091-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QMutex benchmark contains benchmarks for the native mutex type. It was using pthread_mutex_t on Symbian, which isn't the true native mutex type and so isn't really representative of true native performance. Now it uses RMutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The benchmark sometimes hung because wait conditions were sometimes signalled before being waited for. This change adds a real condition to control the interactions. Task-number: QTBUG-13990 Reviewed-by: Shane Kearns

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new test is added in anticipation of a native implementation of QWaitCondition for Symbian. Task-number: QTBUG-13990 Reviewed-by: Shane Kearns

* | | | | Add a once-over unrolled fromLatin1 conversion (32 characters)Thiago Macieira2011-03-271-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | This was suggested by Matthias Kretz on my blog. It improves on GCC (one case up to 5%), but worsens on ICC (up to 5%).

* | | | | Fix a bug in the SSE2 UTF-8 decoder.Thiago Macieira2011-03-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | If the multibyte sequence crossed the end of the SSE2 area, then len would have a wrong value and the data wouldn't be read.
* | | | | Add ARM Neon versions of fromLatin1 and fromUtf8Thiago Macieira2011-03-221-0/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fromLatin1 code is very simple, yet the handwritten assembly performs better due to the use of post-increments. The fromUtf8 code has two alternatives. Neon lacks an instruction similar to SSE2's _mm_movemask_epi8 (PMOVMSKB) which extracts one bit from each byte and stores it in a register. We used that in the UTF-8 code to detect bytes with the highest bit set. To compensate, we used two alternatives: 1) AND the comparison result with a vector containing {128, 64, ...,1 } Do 3 parallel-adds (VPADD.I8), which will make the mask propagate to the lowest component in the vector. Trick found in: http://hilbert-space.de/?p=22 (comment 16-17) 2) Extract the two words from the doubleword Neon register and do the work in ARM assembly. It looks like the latter version is performing better.

* | | | | Add an UTF-8 conversion on trusted data and no BOM.Thiago Macieira2011-03-221-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | This assumes that there are no overlong sequences, no continuation characters without the leading, no missing continuations and no BOM.

* | | | | Add an UTF-8 conversion optimised for ASCII using SSE2Thiago Macieira2011-03-221-1/+54
| | | | | | | | | | | | | | | | | | | | | | | | | This code is 2x faster than the original UTF-8 code and within 35% of the pure Latin1 code
* | | | | Add an UTF-8 conversion code that is optimised for ASCIIThiago Macieira2011-03-221-2/+94
| | | | | | | | | | | | | | | | | | | | This code is ~1.5x faster than the original UTF-8 code
* | | | | Add a stateless copy of the Qt 4.7 UTF-8 codec.Thiago Macieira2011-03-221-0/+99
| | | | | | | | | | | | | | | | | | | | For whatever reason, this code is worse than the stateful code...
* | | | | Add UTF-8 code benchmarksThiago Macieira2011-03-221-0/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also compare to the Latin1 functions. The UTF-8 algorithm in Qt 4.7 right now is 109% slower than the unoptimised Latin-1 algo, 120% than the Qt 4.7 SSE2 code
* | | | | Improve a little more the core loop and propagate to the other codeThiago Macieira2011-03-221-18/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently are that the "improved SSE2" version and the SSE4.1 version are yielding the best results, within 1% of each other. These results are around 20% better than the Qt 4.7 code.
* | | | | Reduce the number of operations in the main loopThiago Macieira2011-03-221-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The more operations there are, the more time it takes. More importantly, the more variables we touch, the more the compiler may want to use the stack instead of registers.
